The bottom board has a foldable slot at its four edges, and each two facing edges are respectively connected to the pair of first side boards and the pair of second side boards. The pair of first side boards respectively has an assembling end at its two outer sides, and the inner edge of the assembling end has a plurality of engaging protrusions. The pair of second side boards respectively has an engaging end at its two outer sides, the engaging end has an engaging slot, and the inner edge of the engaging end has a plurality of assembling apertures connecting to the engaging slot. The assembling end and the engaging end of the first side boards and the second side boards can be alternated, such that the first side boards respectively has the engaging end, and the second side boards respectively has the assembling end.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a box assembly, and more particularlyto a box assembly which is both easy to transport and reducestransportation costs.

2. Description of the Related Art

Currently, a prior art box structure 20, as shown in FIG. 6, is made byway of a plastic injection process or with a welding process usingmetallic materials; therefore, the box structure 20 has a fixed size,which is inconvenient for transportation purposes and increasestransportation costs.

Therefore, it is desirable to provide a box assembly to mitigate and/orobviate the aforementioned problems.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a box assembly.

In order to achieve the above-mentioned objective, an embodiment boxassembly comprises a bottom board respectively connected to a pair offirst side boards and a pair of second side boards. The bottom board hasa foldable slot at its four edges, and each of two facing edges arerespectively connected to the pair of first side boards and the pair ofsecond side boards. The pair of first side boards respectively have anassembling end at its two outer sides, and the inner edge of theassembling end has a plurality of engaging protrusions. The pair ofsecond side boards respectively have an engaging end at its two outersides; the engaging end has an engaging slot, and the inner edge of theengaging end has a plurality of assembling apertures connecting to theengaging slot. The assembling end and the engaging end of the first sideboards and the second side boards can be alternated, such that the firstside boards respectively have the engaging end, and the second sideboards respectively have the assembling end. In order to assemble thebox, first the two identical first side boards are lifted up until theyare vertical to the bottom board as a result of the foldable slotsbetween the bottom board and the first side boards. Then, the twoidentical second side boards are lifted up for assembly with the firstside boards. The engaging slots on the engaging ends at two outer sidesof a second side board engage with the assembling ends of the pair offirst side boards, such that the engaging protrusions on the assemblingends engage with the assembling apertures of the engaging ends.Similarly, another second side board can also be assembled by way of theabove-mentioned steps to finish the assembly process for the entire box.

With the above-mentioned embodiments, the following benefits areobtained: for the box assembly, the box can be disassembled into a flatboard, which is easy to transport and reduces transportation costs.

Other objects, advantages, and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to FIG. 1 and FIG. 2. A box assembly 10 comprises a bottomboard 11 respectively connected to a pair of first side boards 12 and apair of second side boards 13. The bottom board 11 has a foldable slot111 along its four edges, and each of two facing edges are respectivelyconnected to the pair of first side boards 12 and the pair of secondside boards 13. Each of the first side boards 12 has a respectiveassembling end 121 at its two outer sides, and the interior edge of eachassembling end 121 has a plurality of engaging protrusions 122. Each ofthe second side boards 13 has a respective engaging end 131 at its twoouter sides, the engaging ends 131 each having an engaging slot 132, andthe interior edges of the engaging ends 131 have a plurality ofassembling apertures 133 connecting to the engaging slot 132. Theassembling ends 121 and the engaging ends 131 of the first side boards12 and the second side boards 13 may be alternated, such that the firstside boards 12 respectively have the engaging ends 131, while the secondside boards 13 respectively have the assembling ends 121.

For assembly details, please refer to FIGS. 3, 4 and 5. In order toassemble the box 10, first the two identical first side boards 12 may belifted up, as a result of the foldable slots 111 between the bottomboard 11 and the first side boards 12, until the first side boards 12are vertical to the bottom board 11. Then, the two identical second sideboards 13 are lifted up to assemble with the first side boards 12. Theengaging slots 132 on the engaging ends 131 along the two outer sides ofa second side board 13 engage with the assembling ends of the pair offirst side boards 12, such that the engaging protrusions 122 on anassembling end 121 engage with the assembling apertures 133 of anengaging end 131. Similarly, the other second side board 13 can also beassembled by the above-mentioned steps to finish the assembly of theentire box 10.

With the above-mentioned embodiments, the following benefits can beobtained: for the box assembly, the box 10 can be disassembled to form aflat board, which is easy to transport and reduces transportation costs.

Although the present invention has been explained in relation to itspreferred embodiment, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the invention as hereinafter claimed.

1. A box assembly comprising: a bottom board having a foldable portionat its four edges, and each of two facing edges respectively connectedto a pair of first side boards and a pair of second side boards; thepair of first side boards each having an assembling end respectively atits two outer sides, an inner edge of the assembling ends having aplurality of engaging protrusions; the pair of second side boards eachhaving an engaging end respectively at its two outer sides, eachengaging end having an engaging slot, and the inner edge of eachengaging end having a plurality of assembling apertures connecting tothe engaging slot.
